Abstract
A light source device includes a substrate, an upper electrode layer and a lower electrode layer both respectively disposed on two opposite surfaces of the substrate, a light emitting unit mounted on the upper electrode layer, a surrounding frame disposed on the substrate and surrounding the light emitting unit, a conductive unit disposed on the surrounding frame, a light permeable member disposed on the surrounding frame and covering the light emitting unit, and a detecting circuit formed on an outer surface of the light permeable member. The lower electrode layer includes two coplanar sub-layers. The light emitting unit is electrically coupled to one of the two sub-layers through the upper electrode layer. The detecting circuit includes two contacts connected to the conductive unit, and is electrically coupled to the second lower electrode sub-layer by the conductive unit electrically coupled to the other one of the two sub-layers.
